Most equipment rated for 120 V will be damaged by a 240 V connection. Motor windings will overheat and short, so will Transformers, insulation might not hold, most things will get hotter and burn up.
There are quite a number of things that RE made for both 120 and 240 (laptop battery eliminators for example...
The first thing we have to do is clarify the question. A cable rating of 125 volts is an insulation rating of the wire. Like wire with ratings of 300 volts, 600 volts and 1000 volts these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, equipment is tested to destruction. The label that is given to wire as a result of the tests is the highest safest voltages that can be applied to that particular wire. So when you see a wire that has a label stating that it is rated for 300 volts it means that any voltage under and up to 300 volts is safe to apply. So to answer the question yes, the 125 volt insulation rating on the cable can be used to supply a source of 120 volts to a 120 volt rated piece of equipment.
In North America the connection type is 120/240 volt single phase. This allows the use of 120 volts for smaller appliances and equipment along with 240 volts for larger appliances and equipment.
temporary it blows or KABOOOMM....
Because it is a 220 volt outlet instead of a 120 volt outlet. Now, if this is a standard 120 volt outlet that is reading 209 volts then someone has made a mistake in the wiring. You need to call an electrician to straighten this out.
120 volts.
Yes. Circuits in a home are 120 volts but people tend to call them 110 volt circuits. The 120 volts you read on the appliance is the maximum voltage the appliance can handle. The actual voltage you will read at any outlet will range from 110 to 120 volts.
The voltage of 120 volts is more common that the lower voltage of 12 volts.
12 Volts DC
One has an element designed to work on 120 volts, the other has an element designed to work on 240 volts.
When equipment is run at a lower voltage than it is designed for, it does not operate correctly. A light will glow dimly or not at all, a heater produces much less heat. Electronic equipment may not function at all.
